According to CNBC, Meta, Apple and Google are among the tech companies betting that AI wearables such as glasses, rings, charms and pendants can help create a new consumer category, even as privacy concerns and doubts about usefulness grow. Meta recently unveiled its Muse Charm and continues to roll out new versions of its Meta Ray-Ban AI glasses, while OpenAI launched a personal assistant called Dots and Apple showed new devices with AI features on the Watch Series 12.

The article said Oura delayed its expected initial public offering on Tuesday, citing uncertainty in the IPO market, even though it had signaled strong demand for its products. Analysts questioned that explanation. Meta is also facing criticism over its camera-equipped smart glasses, which some users have dubbed "pervert glasses" because of their discreet cameras, and the company last month introduced a camera-free smart glasses option.
